1 Claim.

This invention relates to garments, and particularly to a sleeve structure including an expanding insert, the object being to provide a construction of sleeve which will be conventional in appearance but which at the elbow or other desired points will be expansible to take care of any unusual strains.

Another object of the invention is to provide an expansion insert for sleeve wherein the parts are so formed that when any strain or tension thereon is released the parts will spring back into their normal position.

In the accompanying drawing:

Fig. 1 is a perspective view showing a figure with a garment embodying the invention fitted thereon; V

Fig. 2 is an enlarged fragmentary side view of one of the sleeves shown in Fig. 1;

Fig. 3 is a view similar to Fig. 2 but showin only the sleeve without the cuff or the insert;

Fig. 4 is an elevation of the insert shown in Fig. 2;

Fig. 5 is an enlarged fragmentary sectional View through Fig. 2 on the line 55;

Fig. 6 is a fragmentary sectional view through Fig. 2 approximately on the line 66, the same being on an enlarged scale;

Fig. '7 is a fragmentary view showing part of a sleeve with dot and dash lines indicating how an expansion member may be formed intergral with the sleeve;

Fig. 8 is the next step from Fig. 7 in forming the joint.

Referring to the accompanying drawing by numerals, I indicates a shirt which may be of any desired kind. The shirt I is provided with sleeves 2 and 3 which are identical except that they are for right and left arms. These sleeves are made in the conventional way and are each provided 40 with a conventional cuff 4. However, they are of special construction by reason of the expansion insert or panel 5. The blank of this insert is shown in Fig. 4, from which it will be seen that the insert is formed with parallel side edges 6 and 1 and a. tapering end B. When the insert is mounted in blank 5, edge 6 for instance is stitched to the sleeve 2 along the edge 9 of the insert opening [0. Edge 1 is stitched to the sleeve along the edge ll of the sleeve and the two edges 12 and I3 are stitched together so that the finished structure will appear as indicated in Fig. 2. However, after the blank 5 has been stitched in place it is folded along a central line and then the cuff 4 is placed in position, after which the lines of stitching M are applied. This stitching will secure the side edges 6 and I together at the end I5.

After the insert has been inserted and the cuff l4 applied the parts will appear as shown in Fig. 2. with the insert 5 folded along the central line [6 as indicated in Fig. 5. Normally the opening I0 will remain substantially closed as shown in Figs. 2 and 5, but in case the arms are swung to the position shown in Fig. 1 or some other position whereby tension is brought to bear on the sleeve, the edges 9 and II will separate as indicated in Fig. 1 and the expansion insert 5 will gradually unfold until the parts appear for instance as shown in Fig. 1. It will be noted from Fig. 1 that by reason of the position of the insert it is in what may be termed the outside part of the sleeve whereby it readily expands when the elbow is bent. As soon as the tension is released the parts will automatically return to their former position. 'The threads 14 stitching 15 the edges 6 and 1 together at end 5 will produce an action causing the opening ID to automatically close.

Instead of applying a separate insert or panel as just described, an insert or triangular expansible panel 5' might be provided from the body of the material of sleeve 2. As shown in Fig. '7 the sleeve 2 is made slightly of greater diameter and is folded along the lines I! and [8 until the parts appear as shown in Fig. 8. The corner I9 is then pulled longitudinally of line until the respective wide edges 2! and 22 are parallel with the edge 23 whereupon the stitching [4 could be applied. This gives what may be termed an integral insert or panel which will allow a certain expansion of the sleeve when the elbow of a person Wearing the shirt is bent, although normally the sleeve will remain flap or undistended. As the insert or panel 5' is integral it must taper as shown in Fig. 8, but will readily expand when the elbow is bent by reason of its position on what may be termed the outside part of a sleeve. Where it is a separate piece it may be arranged as shown in Figs. 2, 4 and 5, which will permit a greater expansion at or adjacent the elbow.

I claim:

A shirt provided with a full length sleeve having a cuff with an opening and means for disengageably holding the cuff closed, said sleeve being formed with a fullness from adjacent the elbow to the cuff end, said fullness being formed as a single triangular expansible panel normally lying fiat and extending from adjacent the elbow to the cuff with the point adjacent the elbow of the sleeve and the wide end at the cuff, said panel being part of the outside part of the sleeve so that as the arm of a person using the shirt bends at the elbow the panel will expand approximately from the elbow to the cuff and then move back to a flat position when the arm is straightened, said wide end of said panel being positioned parallel with the edge of said cuff and a seam connecting the cuff to the sleeve and said wide end to the cuff in permanent folded position.
